The area of the circle can be found through the formula:

[tex]\begin{gathered} A=\pi\ast r^2 \\ remember,\text{ } \\ r=\frac{D}{2} \end{gathered}[/tex]

since the diameter is given, find the radius,

[tex]\begin{gathered} r=\frac{18in}{2} \\ r=9in \end{gathered}[/tex]

apply the formula of the area using the approximation for π as 3.14,

[tex]\begin{gathered} A=\pi\ast(9in)^2 \\ A=3.14\ast81in^2 \\ A\approx254.34in^2 \end{gathered}[/tex]

Answer:

The area of the circle is approximately 254.34 in²
